Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, previously called 2019-nCoV) belongs to the family of coronaviruses and, like SARS-CoV, is classified in the genus Betacoronavirus. The new virus has its origin in China. At the end of 2019, it caused a first infection wave that has spread rapidly over the country and worldwide. Just a few days after the first report about patients with pneumonia of unclear origin, SARS-CoV-2 was identified as the causative pathogen.
SARS-CoV-2 is mainly transmitted via aerosols during coughing or sneezing or at close contact with an infected person. The incubation period is three to seven, maximum 14 days. In February 2020, the disease caused by SARS-CoV-2 was named COVID-19 by the WHO. The symptoms of SARS-CoV-19 infection are fever, coughing, breathing difficulties and fatigue. Some patients, especially older and chronically ill persons, develop a severe acute respiratory distress syndrome with sometimes fatal outcome.
